Stop-hinge



UNITED STATES PATENT QFFICE.

HENRY PENNIE, OF BUFFALO, NEW YORK.

STOP-HINGE.

Specification of Letters Patent No. 30,587, dated November 6, 1860.

To all whom it may concern:

Be it known that I, HENRY PENNIE, of Buffalo, in the county of Erie and btate of New York, have invented a new and useful Improvement in Stop-Hinges; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being' had to the accompanying draw ings, making a part of this specification, in which-- Figure l, is an inverted section through the plane indicated by the red line n, in Fig. 3, and showing the hinges folded as when the door is closed. Fig. Q, is the same section but4 showing the hinges unfolded as when the door is open. Fig. 3, is an elevation of which Figs. l and 9. are inverted sections.

Similar letters of reference in each figure, indicate corresponding parts.

vThe nature of this invention consists in the combination of a compound hinge, for carriage and other doors, with an ordinary hinge, thereby constituting a stop hinge, which prevents the door from being opened beyond a certain angle.

To enable those skilled in the art, to make and use my invention, I will proceed to describe its construction and application, having reference to the accompanying drawings.

I use one or more of the ordinary hinges D, with the compound hinge J. The latter consists of wings g, and the connecting links 7L. The wings g, are provided with a fiange f, on three sides, and the connecting links h, are made to fit between these fianges f, when the hinge is folded. The links lz., are hinged to the wings g, at ce,` and c, so as to fold in, as seen in F ig. l, and they are hinged together at This folding joint Z), closes in the opposite direction from those of a, and c, and the shoulders e, Figs. l and 2 should be so fitted as to strike together before the joint comes quite into line with a, and c, as seen in Fig. 2, so that when the door is to be closed, the links L, will readily fold in the proper direction.

By having the links h, close between the flanges f, all vertical strains between the door B when closed and the pillar C, are efectually resisted by the said links It, and

flanges f, thereby avoiding the necessity of the dowel pin heretofore placed in the pillar C, for that purpose.

The compound hinge J, is applied as seen in the drawings, it being placed even with the inside of the pillar C, and door B, and as seen in Fig. l, when the door is shut, no part of the said hinge appears upon the outside of the carriage, whereas with the ordinary hinges and stop strap, the lower hinge necessarily projects out several inches, (similar to D in Fig. l) which projection is more or less according to the swell of the side.77

The door may be taken off at any time, by removing the pins from the hinge D, and the joint l).

The hinge J, affords much greater strength, than the ordinary stop hinge, because the draft from the door B, to the pillar C, is nearly in a direct line from a, to c, instead of being confined to the axis, or near it, of the long or projecting hinge, similar to D.

The strap ordinarily used for the stop, was very liable to become stretched, and often broken or torn off entirely, in either of which cases the door being allowed to swing too far, would be spoiled by striking the wheel, if hung to the back pillar or if hung to the fro-nt one, it would swing against the side of the coach and destroy the panel, or the door, or both; besides, when the strap is used as a stop, it being placed at the bottom of the door, and stretching across from the angles n, Figs. 2 and 3, of the door B, and pillar C, it is frequently the cause of serious accidents', by children catching their feet in it, when alighting and being thrown upon the ground.

What I claim as new and desire to secure by Letters Patent, is-

The combination of the compound hinge J, with an ordinary hinge D, both being arranged and operating substantially in the manner and for the purpose set forth.

HENRY PENNIE.
